Techniques are provided which may be implemented using various methods and/or apparatuses in a vehicle to determine location relative to a roadside unit (RSU) or other nearby point of reference. Vehicles within a pre-designated range or within broadcast distance or otherwise geographically proximate to a roadside unit, through the use of broadcast or other messages sent by the vehicles and/or the RSU may share carrier GNSS phase measurement data, wherein the shared GNSS carrier phase measurement data may be utilized to control and coordinate vehicle movements, velocity and/or position by the RSU and/or to determine location of each vehicle relative to the RSU and/or to other vehicles or determine the absolute location of each vehicle. An RSU may coordinate vehicle access to an intersection, manage vehicle speeds and coordinate or control vehicle actions such as slowing, stopping, and changing lanes or sending a vehicle to a particular location.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the measurement data comprises periodic Global navigation satellite system (GNSS) measurement data or sensor-based measurement data or a combination thereof.
4. The method of claim 1, wherein the device corresponds to a roadside unit (RSU).
6. The method of claim 5, wherein the at least one action request comprises a request to stop and a stopping location.
8. The method of claim 5, wherein the at least one action request comprises a request to change lanes and a direction of lane change.
9. The method of claim 5, wherein the at least one action request comprises a request to coordinate actions with at least one vehicle or to drive at a specified velocity or combination thereof.
11. The method of claim 1, further comprising broadcasting status information or priority information or a combination thereof.
13. The vehicle of claim 12, wherein the measurement data comprises periodic Global navigation satellite system (GNSS) measurement data or sensor-based measurement data or a combination thereof.
15. The vehicle of claim 12, wherein the device corresponds to a roadside unit (RSU).
17. The vehicle of claim 16, wherein the at least one action request comprises a request to stop and a stopping location.
19. The vehicle of claim 17, wherein the at least one action request comprises a request to change lanes and a direction of lane change.
20. The vehicle of claim 17, wherein the at least one action request comprises a request to coordinate actions with at least one vehicle or to drive at a specified velocity or combination thereof.
22. The vehicle of claim 12, wherein the at least one processor is further configured to broadcast status information or priority information or a combination thereof.
24. The vehicle of claim 23, wherein the measurement data comprises periodic Global navigation satellite system (GNSS) measurement data or sensor-based measurement data or a combination thereof.
26. The vehicle of claim 23, wherein the device corresponds to a roadside unit (RSU).
